Need advice on coping

Why do I wake up in panic? It makes no sense. I have no nightmares and don’t remember my dreams at all. My mind just becomes wide awake 2-3 hours before the alarm clock fires, heart racing, and I lie in bed, feeling cold and anxious about nothing in particular. Just anxious! I’m not able to get back to sleep, no matter how hard I try to convince myself that everything’s all right. There’s a pounding in my head, or my ears, that makes it difficult to sleep. If I get up, it all stops. No signs of anxiety or unexplainable fears throughout the day. Only a feeling of exhaustion from sleep deprivation.

Is this normal?

Nothing terrible is happening in my life, and on the days when it happens, I have no big plans, nothing to worry about even subconsciously.
